Researchers at the Korea Rural Development Administration identified specific grain-mix ratios that lower blood glucose and systolic blood pressure in animal models [1].
These findings offer a potential dietary framework for managing diabetes and hypertension through functional foods, providing a scientifically backed alternative to generic mixed-grain diets.
The study was conducted at the National Institute of Food Science in South Korea. Researchers evaluated approximately 30 grain varieties and 80 different mixture combinations to determine the most effective ratios for health management [1].
For diabetes management, the optimal mix consists of 30% oats, 30% sorghum, 15% red bean, 15% finger millet, and 10% proso millet [1]. In animal tests, this specific combination led to a 22.5% decrease in fasting blood glucose compared with diabetic control mice [1].
To address hypertension, the researchers identified a different ratio: 35% sorghum, 35% red bean, and 30% finger millet [1]. This mixture resulted in a 20% decrease in systolic blood pressure compared with hypertensive control mice [1].
"Fasting blood glucose was reduced by 22.5% compared to diabetes-induced mice, and in the case of hypertension, a 20% reduction in systolic blood pressure was achieved," Kim Hyun-joo said [1].
The research suggests that the precise proportion of specific grains, rather than just the presence of whole grains, plays a critical role in the metabolic response of the body.

While the results are promising, the study's reliance on animal models means the findings must be validated through human clinical trials before these ratios can be recommended as medical treatments. If proven effective in humans, this research shifts the focus from general healthy eating to 'precision nutrition,' where specific ingredient ratios are tailored to treat particular chronic conditions.
